(54) КОРПУС ВЫПУСКНОГО КЛАПАНА(54) EXHAUST VALVE BODY
Изобретение относитс к области двигате естроени . Известен корпус выпускного клапана дл двигател внутреннего сгорани , содержащий направл ющую часть с подвод щей и отвод щей полост ми охлаждени , разделенными перегородкой , седельную часть с кольцевой камерой охлаждени , сообщенной каналам с подвод щей и отвод щей полост ми, причем каналы распределены по окружности корпуса равномерно l . Однако в области клапанного седла неравномерно распредел етс температура . Это ухудшает теплоотдачу от клапана к седлу. Цель изобретени - повысить эффек тивность охлаждени . Это достигаетс тем, что подвод ща и отвод ща полости расположены одна на другой в осевом направлении а каналы, сообщающие с подвод щей и отвод щей полост ми, поперемен но чередуютс между собой. На фиг. 1 схематически изображен корпус выпускного клапана с полост ми охлаждени , расположенными одна над другой, частичный разрез; на фиг. 2 - разрез А-А на Фиг.1; на фиг. 3 - разрез Б-Б на фиг.1; на фиг. 4-ксрпус с двум сборными полост ми , наход щимис на одинаковом рассто нии от седельной части, вариант; на фиг. 5 - то же, другой вариант; на фиг. 6 - разрез В-В на фиг. 4; на фиг. 7 - разрез Г-Г на фиг.4. Корпус выпускного клапана 1 содержит направл ющую часть 2 с подвод щей 3 и отвод щей 4 полост ми охлаждени , которые отделены одна от другой перегородкой 5.. Кажда из полостей охлаждени 3, 4 трем каналами сообщена с расположенной в седельной части б кольцевой камерой охлаждени 7, но каналов может быть и больше. Каналы 8-13 равномерно расположены по окружности корпуса 1 и попеременно чередуютс . Каналы 9, 10, 11 сообщеиот подвод щую полость 4 с камерой 8, а каналы 12, 13, 14 сообщают отвод щую полость 5 с камерой 8. Полость 4 посредством соединительного ниппел 15 присоединена к источнику охлгикдающего средства (не показан ) . Дл отвода охлёикдающего средства КЗ полостн S каналом 16 св занаThe invention relates to the field of engine management. An exhaust valve housing for an internal combustion engine is known, comprising a guide part with inlet and outlet cooling cavities separated by a septum, a seat part with an annular cooling chamber communicated to the channels with inlet and outlet cavities, the channels being distributed around the circumference of the housing evenly l. However, the temperature is unevenly distributed in the valve seat area. This impairs the heat transfer from the valve to the seat. The purpose of the invention is to increase the cooling efficiency. This is achieved by the fact that the inlet and outlet cavities are located one on another in the axial direction, and the channels communicating with the inlet and outlet cavities alternate between each other. FIG. Figure 1 shows schematically an exhaust valve body with cooling cavities arranged one above the other, partly cut away; in fig. 2 shows section A-A in FIG. in fig. 3 shows a section BB in FIG. in fig. A 4-cprpus with two teams cavities located at the same distance from the saddle, option; in fig. 5 - the same, another option; in fig. 6 is a sectional view BB in FIG. four; in fig. 7 - section GGD in figure 4. The body of the exhaust valve 1 contains a guide part 2 with a supply 3 and a discharge 4 cooling cavities, which are separated from one another by a partition 5. Each of the cooling cavities 3, 4 with three channels communicates with the annular cooling chamber 7 located in the saddle section but channels may be more. The channels 8-13 are evenly spaced around the circumference of the housing 1 and alternately alternate. Channels 9, 10, 11 communicate the supply cavity 4 with the chamber 8, and channels 12, 13, 14 communicate the outlet cavity 5 with the chamber 8. The cavity 4 is connected to the source of cooling means (not shown) by means of a connecting nipple 15. To divert the KZ short-circuiting cooling agent by channel 16, it is connected
с соединительным ниппелем 17, которчлй магистралью св зан с местом вывода охлаждающего средства.a connecting nipple 17, which is connected to the outlet of the coolant.
В зоне канала 18 дл выхода отработавших газов из камеры сг.орани каналы 13, 12, 14 и 9, 11, 10 выполнены в виде сверлений, в стойках 1 В зоне Iполости 5 каналы 13, 12, 14 расположены в выступающих част х 20 стенки корпуса 1.Полости 4,5 (фиг.47 ) расположены приблизительно на одинаковом рассто нии от седельной части и кажда обхватывает часть окружп ности 1. Каналы 9 и 10 пр молинейно отход т от полости 4 и выполнены в виде сверлений, а канал 11 через радиальное сверление 21 в поперечине 22 св зан с щелевой полостью 23. Эта полость 23 сверлением 24 св зана с полостью 4. Отвод ща полость 5 непосредственно через каналы 13 и 12 св зана с кольцевой камерой 8. Кроме того, полость 5 через радиальное сверление, 25, щелевую полость 26 и сверление 27 в поперечине 28 соединена с каналом 14, который находитс в части корпу а 1 противоположной полости 5. Отверсти в стенках корпуса эЪкрыгы заглушками 29, 30.In the area of the channel 18 for exhaust gas exiting the combustion chamber, the channels 13, 12, 14 and 9, 11, 10 are made in the form of drillings, in the racks 1 In the zone I of the cavity 5, the channels 13, 12, 14 are located in projecting parts 20 of the wall 1.Cavities 4.5 (Fig.47) are located approximately at the same distance from the saddle part and each covers part of the circle 1. Channels 9 and 10 directly extend from cavity 4 and are drilled, and channel 11 through radial drilling 21 in crossmember 22 is connected to a slot cavity 23. This cavity 23 by drilling 24 is connected to cavity 4 The outlet cavity 5 is directly connected through channels 13 and 12 to the annular chamber 8. In addition, the cavity 5 through radial drilling, 25, the slot cavity 26 and the drilling 27 in cross member 28 is connected to channel 14, which is located in the housing part 1 opposite cavity 5. Holes in the shell eKkrygy caps 29, 30.
При работе через ниппель 1 в подвод щую полость 4 подаётс охлаждак цее средство, которое «о каналам 9, 11, 10 поступает в камеру 8. Из камеры охлаждающее средство по каналам 13, 12, 14, чередующимс с каналами 9, 11, 10, поступает в отвод щую полость 5, откуда по каналу 16 и через ниппель 17 может быть удалено.When operating through the nipple 1, cooling means is supplied to the inlet cavity 4, which means about channels 9, 11, 10 enters chamber 8. From the chamber, coolant flows through channels 13, 12, 14 alternating with channels 9, 11, 10, enters the discharge cavity 5, from where it can be removed through the channel 16 and through the nipple 17.
Благодар чередованию подвод щих 9, 10, 11 и отвод щих 12, 13, 14 каналов обеспечиваетс благопри тное распределение температуры в седельной части при соответствук цем увеличении теплопередачи от корпуса клапана к седельной части.Due to the alternation of the supplying 9, 10, 11 and exhausting 12, 13, 14 channels, the temperature in the seat part is favorably distributed, with a corresponding increase in heat transfer from the valve body to the seat part.
